Properly managing aquatic organisms is crucial, including protecting endemic species and controlling invasive species. From a circular economy perspective, the sustainable use of aquatic species as a source of bioactive molecules is an area that is increasingly being explored. This includes the use of non-edible portions of seafood, which could pose considerable risks to the environment due to current methods of disposal. Therefore, it is of paramount importance to ensure that the exploitation of these resources does not result in the transfer of pollutants to the final product. This study analyzed two types of non-edible parts from the crayfish : the abdominal portion of the exoskeleton (AbE) and the whole exoskeleton (WE), including the cephalothorax. These portions could potentially be utilized in the context of eradication activities regulated by local authorities. A screening analysis of four classes of pollutants, including pesticides, per- and polyfluoroalkyl substances (PFAS), phthalic acid esters (PAEs), and trace elements (TEs), was performed. The only analytes detected were TEs, and significant differences in the contamination profile were found between AbE and WE. Nevertheless, the levels recorded were comparable to or lower than those reported in the literature and below the maximum levels allowed in the current European legislation for food, suggesting that their potential use is legally permitted. In terms of scalability, the utilization of the entire non-edible portion would represent a sustainable solution for the reuse of waste products.
妥善管理水生生物至关重要，包括保护本地物种和控制入侵物种。从循环经济的角度来看，将水生物种作为生物活性分子来源的可持续利用是一个越来越受到探索的领域。这包括利用海鲜的不可食用部分，由于目前的处理方法，这些部分可能对环境造成相当大的风险。因此，确保这些资源的开发不会导致污染物转移到最终产品中至关重要。本研究分析了小龙虾的两种不可食用部分：外骨骼的腹部部分（AbE）和整个外骨骼（WE），包括头胸部。这些部分有可能在地方当局监管的根除活动中得到利用。对包括农药、全氟和多氟烷基物质（PFAS）、邻苯二甲酸酯（PAEs）和微量元素（TEs）在内的四类污染物进行了筛选分析。唯一检测到的分析物是TEs，并且发现AbE和WE之间的污染情况存在显著差异。然而，记录的水平与文献报道的相当或更低，且低于当前欧洲食品立法允许的最高水平，这表明它们的潜在用途在法律上是允许的。在可扩展性方面，利用整个不可食用部分将是一种可持续的解决方案，用于废物产品的再利用。
